Maxitrol R325C10-412 Spring

The Maxitrol R325C10-412 is a field-critical violet replacement spring engineered specifically for the Maxitrol 325-3 series lever-acting gas regulators. This high-performance component allows technicians to achieve a precise outlet pressure range of 4 to 12 inches water column (w.c.), making it a staple for localized pressure adjustments in residential, commercial and industrial gas piping systems. Designed to maintain the regulator's high-leverage valve linkage integrity, it ensures consistent dead-end lockup and stable control from full flow down to pilot flow.

Constructed for compatibility with natural gas, LP, and mixed fuel types, this 4-12" w.c. violet spring is the standard choice when converting or fine-tuning Maxitrol 325-3 units to meet specific appliance manifold requirements. As a veteran-grade HVACR part, it handles ambient temperatures from -40 to 205°F without compromising tension or calibration. When installing, ensure the R325C10-412 is seated correctly within the adjustment stack to prevent erratic pressure fluctuations and maintain ANSI Z21.18 compliance for appliance regulation.

• Specifically calibrated for the Maxitrol 325-3 series regulator.
• Provides a reliable 4-12" w.c. pressure range (Violet color-coded).
• Supports positive dead-end lockup for safer system operation.
• Maintains precise gas flow control across all compatible fuel gases.
• Durable construction prevents spring fatigue in high-demand environments.

• How do I identify this spring in the field? This spring is color-coded Violet to distinguish its 4-12" w.c. range from others in the 325-3 series.
• Is this compatible with the 325-5 or 325-7 series? No, the R325C10-412 is specifically sized for 325-3 series housings; always check your regulator model before installation.
• Does this spring work with LP gas? Yes, this component is suitable for natural gas, manufactured, mixed, and liquefied petroleum (LP) gases.
